2006 hemi Ram weird shifting
Posted: Mon Mar 16, 2009 3:37 pm
2006 Hemi Ram 1500, U7137 set at 91 octane, Green CAD. When Driving at a steady speed and flooring it, the tranny will downshift one gear then another for a half second. Really bad bang and vibration. Afraid to try that with 5th wheel trailer hooked up. Is this because of some TCM adaptive part that the tranny doesn't undersand with new tune and will it go away? Do we have to manually set WOT shift points?
